Sorry GB. My pm answer to you was wrong.
Two bombs should be either choice among the 30 to 100kg.
Let me correct as follows -

Ki44-1 had no bombs.
Ki44-2 could carry two 30kg to 100kg bombs under the wing.
A few early Ki-44-2a could carry a 250kg bomb under the fuselage as an experimental model.
Two 125 litters drop tanks could be attached under the inner wing for the all Ki44 but the early 5 experimental Ki44-1 which had a drop tank under the fuselage.
The under carriages for the bombs and the drop tanks were separated but they were common for a few later Ki44-2c.
